If gpu_mem is not specified we will increase gpu memory from 64M to 76M and arm memory from 944M to 948M as the extra gpu memory improves Chromium's hardware video decode performance. Compute Module hardware A Raspberry Pi Compute Module (CM) is a compact version of a standard Raspberry Pi single-board computer (SBC) designed primarily for embedded and industrial applications. However you could set it manually on your needs as well. For the change to take effect, Raspberry Pi needs to be restarted. [73] Boot settings, low-level device configurations, various memory settings, and power management settings are often available in the PC BIOS. A Compute Module contains the core components of a Raspberry Pi but without the standard connectors like HDMI, USB, or Ethernet.
